L’agriculture intelligente face au climat

This paper estimates the economic impacts of climate change over the Brazilian regions until the end of the century. We estimate the direct and indirect impact of the projected changes in climate on the yield of the country’s main crops. The results point to a broad spatial heterogeneity of impacts across the country. Using the extreme scenarios created by the Intergovernmental Panel on Climate Change (IPCC) (RCP 2.6 and 8.5), our predictions indicate that the average annual losses ...

Within the context of the United Nations Food Systems Summit taking place in September 2021, this brief discusses key drivers of food systems in Africa, as well as the challenges and opportunities for transformation. It concludes with specific policy options that could considerably accelerate progress towards the transformation of food systems across the continent. Specifically, this policy brief makes five recommendations: it recommends that investment in research and development f ...

Low-productivity, subsistence-smallholder agriculture everywhere faces tremendous new challenges, in addition to decades-old constraints. Smallholders are threatened by being bypassed by the rise and dominance of domestic and global value chains (DVCs, GVCs). They are also being threatened by global warming, which is already rewriting the basic parameters of temperature and precipitation on which their entire activities depend. These global forces are much too powerful for any farmi ...

If there is any silver lining to this COVID-19 pandemic, it is the realization of the importance of some of what we hold most dear: food security, and the foundations of hope. Food Security: Those of us who enjoy food security realize how much we depend on every link of the agri-food chain. For urbanites, a first sign that this chain is broken is empty shelves—supply shortages and panic buying. We suddenly appreciate the appeal of food self-sufficiency or food sovereignty: develop ...

Across Africa, many rural communities still depend on manual and animal power for their farm needs, whether it is for production, harvesting or postharvest activities. In fact, in sub-Saharan Africa, engine power represents a meagre 10 per cent of all energy used on farms, compared to 50 per cent in developing regions. Without access to mechanised tools and technologies, farming is a tough, laborious and time-consuming process. Farmers are often left with small harvests, low income ...

The Atlantic Current’s 6th edition provides overview, fresh insights, latest data, and broader analysis on the Atlantic space’s current challenges, as well as their implications for the South. Different chapters explore emerging trends and critical issues, such as the World Trade Organization reform, Brexit and the future of EU, the expansion of militancy in the Sahel and Coastal Africa, the role of cultural diplomacy and the deepening of Sino-African relations within a shifting an ...

Subsidizing fertilizer prices has been a popular policy tool to increase fertilizer use, but should it be? The main message of this Policy Brief is that it should not be, despite its appeal to politicians and recipient farmers alike. Instead, policy makers should seriously consider a holistic approach to promoting fertilizer. A holistic approach has the potential of effectively addressing a range of key interlocking constraints which condemn smallholders to low input, low productivi ...

This paper is about the basic principles which should guide fertilizer policy for smallholder agriculture in sub-Saharan Africa It is not about detailed country-specific prescriptions on the “how” of policy. This important task should constitute the substance of detailed country studies. The overarching goal here is to use fertilizer to spearhead and sustain an African Green Revolution (GR). In this paper, fertilizer use is not considered as an end in itself, but as a necessary mean ...

Commodity prices were once again marked by significant volatility in 2017 and 2018. While there are many economic factors to explain this, politics were also present—trade tensions between China and the United States and, more generally, a rise in uncertainties—weighing upon the global macroeconomic outlook and the ‘dynamism of the markets’. Africa, which has countries with strong growth rates, has, however, been able to show solid economic performance, and this trajectory is not li ...

The author is an alumnus of the 2018 Atlantic Dialogues Emerging Leaders program Arable land per capita availability has been steadily decreasing over the last decades, from 0.5 hectare per capita in 1945 to 0.2 hectares per capita in 2016. Worldwide farmers have been, more or less, addressing the intensification challenge by incorporating new technologies, products, and techniques into their farming systems. The intensification challenge also implied a consolidation of the farming ...
